from Peak site...
"Peak LED Solutions has chosen to use an advanced product from a specialty manufacture that uses a proprietary method to produce an LED —White" color output that closely matches EEW. We call this LED —SNOW" white. The nominal color output is between the printing and publishing industry standard of ISO 3664, (approved March 21, 2000 ), at 5000 degrees Kelvin and EEW of about 5500 degrees Kelvin. We are currently using a third generation of this product. The first generation produced a nominal output of 12,000 mcd. The latest version is in the 22,000 mcd nominal output range at 20 mA current. This is between a —U" and a —V" bin output of another popular LED manufacturer. (The —V" bins LEDs, according to the information from that manufacturer, are almost impossible at present to get. Most get —T" with a limited number in the —U" bin."
there are some beam pics in my groupbuy and Dorcy AAA threads - am in process of removing about 40 "other" LEDs from some of my lights and replacing them with the snow 29's.
I can post pics of my Streamlight 4xAA 7 LED light if anyone is interested (stock, vs "other", vs Snow)
